I was actually waiting for you to analyze this position with the CM9000, because
it's far the fastest engine for quick mates.
I sincerely doubted that there is a mate-in-10, but now that you have confirmed
it, I'm almost certain that there is none.
Several strong engines that I've tried don't see any mate after hours.
As I said, a strong player/engine could easily checkmate a weak human player
within 10 moves, but it doesn't look like a mate-in-10.
